This post is the second in a series of posts highlighting interviews with Philadelphia area biotech startup CEO’s and show how a vibrant biotech startup scene is evolving in the city as well as the Delaware Valley area. Philadelphia has been home to some of the nation’s oldest biotechs including Cephalon, Centocor, hundreds of spinouts from a multitude of universities as well as home of the first cloned animal (a frog), the first transgenic mouse, and Nobel laureates in the field of molecular biology and genetics. Although some recent disheartening news about the fall in rankings of Philadelphia as a biotech hub and recent remarks by CEO’s of former area companies has dominated the news, biotech incubators like the University City Science Center and Bucks County Biotechnology Center as well as a reinvigorated investment community (like PCCI and MABA) are bringing Philadelphia back. And although much work is needed to bring the Philadelphia area back to its former glory days (including political will at the state level) there are many bright spots such as the innovative young companies as outlined in these posts.

efavirenz_med-2In today’s post, I had the opportunity to talk with molecular modeler Charles H. Reynolds, Ph.D., founder and CEO of Gfree Bio LLC, a computational structure-based design and modeling company based in the Pennsylvania Biotech Center of Bucks County. Gfree is actually one of a few molecular modeling companies at the Bucks County Biotech Center (I highlighted another company RabD Biotech which structural computational methods to design antibody therapeutics).

Below is the interview with Dr. Reynolds of Gfree Bio LLC and Leaders in Pharmaceutical Business Intelligence (LPBI):

LPBI: Could you briefly explain, for non-molecular modelers, your business and the advantages you offer over other molecular modeling programs (either academic programs or other biotech companies)? As big pharma outsources more are you finding that your company is filling a needed niche market?

GfreeBio: Gfree develops and deploys innovative computational solutions to accelerate drug discovery. We can offer academic labs a proven partner for developing SBIR/STTR proposals that include a computational or structure-based design component. This can be very helpful in developing a successful proposal. We also provide the same modeling and structure-based design input for small biotechs that do not have these capabilities internally. Working with Gfree is much more cost-effective than trying to develop these capabilities internally. We have helped several small biotechs in the Philadelphia region assess their modeling needs and apply computational tools to advance their discovery programs. (see publication and collaboration list here).

LPBI: Could you offer more information on the nature of your 2014 STTR award?

GfreeBio: Gfree has been involved in three successful SBIR/STTR awards in 2014.   I am the PI for an STTR with Professor Burgess of Texas A&M that is focused on new computational and synthetic approaches to designing inhibitors for protein-protein interactions. Gfree is also collaborating with the Wistar Institute and Phelix Therapeutics on two other Phase II proposals in the areas of oncology and infectious disease.

LPBI: Why did you choose the Bucks County Pennsylvania Biotechnology Center?

GfreeBio: I chose to locate my company at the Biotech Center because it is a regional hub for small biotech companies and it provides a range of shared resources that are very useful to the company. Many of my most valuable collaborations have resulted from contacts at the center.

LPBI: The Blumberg Institute and Natural Products Discovery Institute has acquired a massive phytochemical library. How does this resource benefit the present and future plans for GfreeBio?

GfreeBio: To date Gfree Bio has not been an active collaborator with the Natural Products Insititute, but I have a good relationship with the Director and that could change at any time.

LPBI: Was the state of Pennsylvania and local industry groups support GfreeBio’s move into the Doylestown incubator? Has the partnership with Ben Franklin Partners and the Center provided you with investment and partnership opportunities?

GfreeBio: Gfree Bio has not been actively seeking outside investors, at least to date. We have been focused on growing the company through collaborations and consulting relationships. However, we have benefitted from being part of the Keystone Innovation Zone, a state program that provides incentives for small technology-based businesses in Pennsylvania.

LPBI: You will be speaking at a conference in the UK on reinventing the drug discovery process through tighter collaborations between biotech, academia, and non-profit organizations.  How do you feel the Philadelphia area can increase this type of collaboration to enhance not only the goals and missions of nonprofits, invigorate the Pennsylvania biotech industry, but add much needed funding to the local academic organizations?

GfreeBio: I think this type of collaboration across sectors appears to be one of the most important emerging models for drug discovery.   The Philadelphia region has been in many ways hard hit by the shift of drug discovery from large vertically integrated pharmaceutical companies to smaller biotechs, since this area was at the very center of “Big Pharma.” But I think the region is bouncing back as it shifts more to being a center for biotech. The three ingredients for success in the new pharma model are great universities, a sizeable talent pool, and access to capital. The last item may be the biggest challenge locally. The KIZ program (Keystone Innovation Zone) is a good start, but the region and state could do more to help promote innovation and company creation. Some other states are being much more aggressive.

LPBI: In addition, the Pennsylvania Biotechnology Center in Bucks County appears to have this ecosystem: nonprofit organizations, biotechs, and academic researchers. Does this diversity of researchers/companies under one roof foster the type of collaboration needed, as will be discussed at the UK conference? Do you feel collaborations which are in close physical proximity are more effective and productive than a “virtual-style” (online) collaboration model? Could you comment on some of the collaborations GfreeBio is doing with other area biotechs and academics?

GfreeBio: I do think the “ecosystem” at the Pennsylvania Biotechnology Center is important in fostering new innovative companies. It promotes collaborations that might not happen otherwise, and I think close proximity is always a big plus. As I mentioned before, many of the current efforts of Gfree have come from contacts at the center.   This includes SBIR/STTR collaborations and contract work for local small biotech companies.

LPBI: Thompson Reuters just reported that China’s IQ (Innovation Quotient) has risen dramatically with the greatest patents for pharmaceuticals and compounds from natural products. Have you or your colleagues noticed more competition or business from Chinese pharmaceutical companies?

GfreeBio: The rise of Asia, particularly China, has been one of the most significant recent trends in the pharmaceutical industry. Initially, this was almost exclusively in the CRO space, but now China is aggressively building a fully integrated domestic pharmaceutical industry.

LPBI: How can the Philadelphia ecosystem work closer together to support greater innovation?

GfreeBio: A lot has happened in recent years to promote innovation and company creation in the region. There could always be more opportunities for networking and collaboration within the Philadelphia community. Of course the biggest obstacle in this business is often financing. Philadelphia needs more public and private sources for investment in startups.

LPBI: Thank you Dr. Reynolds.

I am intending to do a series of posts highlighting interviews with Philadelphia area biotech startup CEO’s and show how a vibrant biotech startup scene is evolving in the city as well as the Delaware Valley area. Philadelphia has been home to some of the nation’s oldest biotechs including Cephalon, Centocor, hundreds of spinouts from a multitude of universities as well as home of the first cloned animal (a frog), the first transgenic mouse, and Nobel laureates in the field of molecular biology and genetics. Although some recent disheartening news about the fall in rankings of Philadelphia as a biotech hub and recent remarks by CEO’s of former area companies has dominated the news, biotech incubators like the University City Science Center and Bucks County Biotechnology Center as well as a reinvigorated investment community (like PCCI and MABA) are bringing Philadelphia back. And although much work is needed to bring the Philadelphia area back to its former glory days (including political will at the state level) there are many bright spots such as the innovative young companies as outlined in these posts.

First up I got to talk with Florian Schodel, M.D., Ph.D., CEO of Philimmune, which provides expertise in medicine, clinical and regulatory development and analytical sciences to support successful development and registration of vaccines and biologics. Before founding Philimmune, Dr. Schodel was VP in Vaccines Clinical Research of Merck Research Laboratories and has led EU vaccine clinical trials and the clinical development of rotavirus, measles, mumps, hepatitis B, and rubella vaccines. In addition Dr. Schodel and Philimmune consult on several vaccine development efforts at numerous biotech companies including:

 

\His specialties and services include: vaccines and biologics development strategy, clinical development, clinical operations, strategic planning and alliances, international collaborations, analytical and assay development, project and portfolio integration and leadership.

Successful development of vaccines and biologics poses some unique challenges: including sterile manufacturing and substantial early capital investment before initiated clinical trials, assay development for clinical trial support, and unique trail design. Therefore vaccines and biologics development is a highly collaborative process between several disciplines.

The Philadelphia area has a rich history in vaccine development including the discovery and development of the rubella, cytomegaolovirus, a rabies, and the oral polio vaccine at the Wistar Institute. Dr. Schodel answered a few questions on the state of vaccine development and current efforts in the Philadelphia area, including recent efforts by companies such as GSK’s efforts and Inovio’s efforts developing an Ebola vaccine.

In his opinion, Dr. Schodel believes our biggest hurdle in vaccine development in a societal issue, not a preclinic development issue. Great advances have been made to speed the discovery process and enhance quality assurance of manufacture capabilities like

however there has not been a great history or support for developing vaccines for the plethora of infectious diseases seen in the developing world. As Dr. Schodel pointed out, there are relatively few players in the field, and tough to get those few players excited for investing in new targets.

 

However, some companies are rapidly expanding their vaccine portfolios including

 

 

Why haven’t 3rd world countries developed their own vaccine programs?

 

  1. Hard to find partners willing to invest and support development
  2. Developing nations don’t have the money or infrastructure to support health programs
  3. Doctors in these countries need to be educated on how to conduct trials, conduct vaccine programs like Gates Foundation does. For more information see Nature paper on obstacles to vaccine introduction in third world countries.

 

Lastly, Dr. Schodel touched on a growing area, cancer vaccine development. Recent advances in bladder cancer vaccine, cervical, and promising results in an early phase metastatic breast cancer vaccine trial and phase I oral cancer vaccine trial have reinvigorated this field of cancer vaccinology.

Snoopy - Charlie happiness

Snoopy – Charlie happiness

This work has been a coming to terms with my scientific and medical end of career balancing in a difficult time after retiring, but it has been rewarding.  In the clinical laboratories, radiology, anesthesiology, and in pharmacy, there has been some significant progress in support of surgical, gynecological, developmental, medical practices, and even neuroscience directed disciplines, as well as epidemiology over a period of half a century.  Even then, cancer and neurological diseases have been most difficult because the scientific basic research has either not yet uncovered a framework, or because that framework has proved to be multidimensional.  In the clinical laboratory sciences, there has been enormous progress in instrumental analysis, with the recent opening of molecular methods not yet prepared for routine clinical use, which will be a very great challenge to the profession, which has seen the development of large sample volume, multianalite, high-throughput, low-cost support emerging for decades.  The capabilities now underway will also enrrich the the capabilities of the anatomic pathology suite and the capabilities of 3-dimensional radiological examination.  In both pathology and radiology, we have seen the division of the fields into major subspecialties.  The development of the electronic health record had to take lessons from the first developments in the separate developments of laboratory, radiology, and pharmacy health record systems, to which were added, full cardiology monitoring systems.  These have been unintegrated.  This made it difficult to bring forth a suitable patient health record because the information needed to support decision-making by practitioners was in separate “silos”.  The mathematical methods that are being applied to the -OMICS sciences, can be brought to bear on the simplification and amplification of the clinicians’ ability to make decisions with near “errorless” discrimination, still allowing for an element of “art” in carrying out the history, physical examination, and knowledge unique to every patient.

We are at this time opening a very large, complex, study of biology in relationship to the human condition.  This will require sufficient resources to be invested in the development of these for a better society, which I suspect, will go on beyond the life of my grandchildren.  Hopefully, the long-term dangers of climate change will be controlled in that time.  As a society, or as a group of interdependent societies, we have no long term interest in continuing self-destructive behaviors that have predominated in the history of mankind.  I now top off these discussions with some further elucidation of what lies before us.

Metabolomics and systems pharmacology: why and how to model the human metabolic network for drug discovery

Douglas B. Kell and Royston Goodacre
School of Chemistry and Manchester Institute of Biotechnology, The University of Manchester, Manchester, UK

Metabolism represents the ‘sharp end’ of systems biology,

  • because changes in metabolite concentrations
  • are necessarily amplified relative to
  • changes in the transcriptome, proteome and enzyme activities,
  • which can be modulated by drugs.

To understand such behaviour, we therefore need
(and increasingly have)

  • reliable consensus (community) models of the human metabolic network
  • that include the important transporters.

Small molecule ‘drug’ transporters are in fact metabolite transporters,

  • because drugs bear structural similarities to metabolites known
  • from the network reconstructions and from measurements of the metabolome.

Recon2 represents the present state-of-the-art human metabolic
network reconstruction; it can predict inter alia:

  1. the effects of inborn errors of metabolism;
  2. which metabolites are exometabolites, and
  3. how metabolism varies between tissues and cellular compartments.

Even these qualitative network models are not yet complete. As our
understanding improves so do we recognize more clearly the need for a systems (poly)pharmacology.

Modelling biochemical networks – why we do so
There are at least four types of reasons as to why one would wish to model a biochemical network:

  1. Assessing whether the model is accurate, in the sense that it
    reflects – or can be made to reflect – known experimental facts.
  2. Establishing what changes in the model would improve the
    consistency of its behaviour with experimental observations
    and improved predictability, such as with respect to metabolite
    concentrations or fluxes.
  3. Analyzing the model, typically by some form of sensitivity
    analysis, to understand which parts of the system contribute
    most to some desired functional properties of interest.
  4. Hypothesis generation and testing, enabling one to analyse
    rapidly the effects of manipulating experimental conditions in
    the model without having to perform complex and costly
    experiments (or to restrict the number that are performed).

In particular, it is normally considerably cheaper to perform
studies of metabolic networks in silico before trying a smaller
number of possibilities experimentally; indeed for combinatorial
reasons it is often the only approach possible. Although
our focus here is on drug discovery, similar principles apply to the
modification of biochemical networks for purposes of ‘industrial’
or ‘white’ biotechnology.
Why we choose to model metabolic networks more than

  • transcriptomic or proteomic networks

comes from the recognition – made particularly clear

  • by workers in the field of metabolic control analysis

– that, although changes in the activities of individual enzymes tend to have

  • rather small effects on metabolic fluxes,
  • they can and do have very large effects on metabolite concentrations (i.e. the metabolome).

Modelling biochemical networks – how we do so

Although one could seek to understand the

  1. time-dependent spatial distribution of signalling and metabolic substances within indivi
    dual cellular compartments and
  2. while spatially discriminating analytical methods such as Raman spectroscopy and
    mass spectrometry do exist for the analysis of drugs in situ,
  • the commonest type of modelling, as in the spread of substances in
    ecosystems,
  • assumes ‘fully mixed’ compartments and thus ‘pools’ of metabolites.

Although an approximation, this ‘bulk’ modelling will be necessary for complex ecosystems such as humans where, in addition to the need for tissue- and cell-specific models, microbial communities inhabit this superorganism and the
gut serves as a source for nutrients courtesy of these symbionts.

Topology and stoichiometry of metabolic networks as major constraints on fluxes
Given their topology, which admits a wide range of parameters for
delivering the same output effects and thereby reflects biological
robustness,

  • metabolic networks have two especially important constraints that assist their accurate modelling:

(i) the conservation of mass and charge, and
(ii) stoichiometric and thermodynamic constraints.

These are tighter constraints than apply to signalling networks.

New developments in modelling the human metabolic network
Since 2007, several groups have been developing improved but nonidentical models of the human metabolic network at a generalised level and in tissue-specific forms. Following a similar community-driven strategy in Saccharomyces cerevisiae, surprisingly similar to humans, and in Salmonella typhimurium,

we focus in particular on a recent consensus paper that provides a highly curated and semantically annotated model of the human metabolic network, termed

In this work, a substantial number of the major groups active in this area came together to provide a carefully and manually constructed/curated network, consisting of some 1789 enzyme-encoding genes, 7440 reactions and 2626 unique metabolites distributed over eight cellular compartments.  A variety of dead-end metabolites and blocked reactions remain (essentially orphans and widows). But Recon2 was able to

  • account for some 235 inborn errors of metabolism,
  • a variety of metabolic ‘tasks’ (defined as a non-zero flux through a reaction or through a pathway leading to the production of a metabolite Q from a metabolite P).
  • filtering based on expression profiling allowed the construction of 65 cell-type-specific models.
  • Excreted or exometabolites are an interesting set of metabolites,
  • and Recon2 could predict successfully a substantial fraction of those

Role of transporters in metabolic fluxes

The uptake and excretion of metabolites between cells and their macrocompartments

  • requires specific transporters and in the order of one third of ‘metabolic’ enzymes,
  • and indeed of membrane proteins, are in fact transporters or equivalent.

What is of particular interest (to drug discovery), based on their structural similarities, is the increasing recognition (Fig. 3) that pharmaceutical drugs also

  • get into and out of cells by ‘hitchhiking’ on such transporters, and not –

to any significant extent –

  • by passing through phospholipid bilayer portions
    of cellular membranes.

This makes drug discovery even more a problem of systems biology than of biophysics.

role of solute carriers and other transporters in cellular drug uptake

role of solute carriers and other transporters in cellular drug uptake

Two views of the role of solute carriers and other transporters in cellular drug uptake. (a) A more traditional view in which all so-called ‘passive’drug uptake occurs through any unperturbed bilayer portion of membrane that might be present.
(b) A view in which the overwhelming fraction of drug is taken up via solute transporters or other carriers that are normally used for the uptake of intermediary metabolites. Noting that the protein:lipid ratio of biomembranes is typically 3:1 to 1:1 and that proteins vary in mass and density (a typical density is 1.37 g/ml) as does their extension, for example, normal to the ca. 4.5 nm lipid bilayer region, the figure attempts to portray a section of a membrane with realistic or typical sizes and amounts of proteins and lipids. Typical protein areas when viewed normal to the membrane are 30%, membranes are rather more ‘mosaic’ than ‘fluid’ and there is some evidence that there might be no genuinely ‘free’ bulk lipids (typical phospholipid masses are 750 Da) in biomembranes that are uninfluenced by proteins. Also shown is a typical drug: atorvastatin (LipitorW) – with a molecular mass of 558.64 Da – for size comparison purposes. If proteins are modelled as
cylinders, a cylinder with a diameter of 3.6 nm and a length of 6 nm has a molecular mass of ca. 50 kDa. Note of course that in a ‘static’ picture we cannot show the dynamics of either phospholipid chains or lipid or protein diffusion.

‘Newly discovered’ metabolites and/or their roles

To illustrate the ‘unfinished’ nature even of Recon2, which concentrates on the metabolites created via enzymes encoded in the human genome, and leaving aside the more exotic metabolites of drugs and foodstuffs and the ‘secondary’ metabolites of microorganisms, there are several examples of interesting ‘new’ (i.e. more or less recently recognised) human metabolites or roles thereof that are worth highlighting, often from studies seeking biomarkers of various diseases – for caveats of biomarker discovery, which is not a topic that we are covering here, and the need for appropriate experimental design. In addition, classes of metabolites not well represented in Recon2 are oxidised molecules such as those caused by nonenzymatic reaction of metabolites with free radicals such as the hydroxyl radical generated by unliganded iron. There is also significant interest in using methods of determining small molecules such as those in the
metabolome (inter alia) for assessing the ‘exposome’, in other words all the potentially polluting agents to which an
individual has been exposed.

Recently discovered effects of metabolites on enzymes 

Another combinatorial problem reflects the fact that in molecular enzymology it is not normally realistic to assess every possible metabolite to determine whether it is an effector (i.e.activator or inhibitor) of the enzyme under study. Typical proteins are highly promiscuous and there is increasing evidence for the comparative promiscuity of metabolites
and pharmaceutical drugs. Certainly the contribution of individual small effects of multiple parameter changes can have substantial effects on the potential flux through an overall pathway, which makes ‘bottom up’ modelling an inexact science. Even merely mimicking the vivo (in Escherichia coli) concentrations of K+, Na+, Mg2+, phosphate, glutamate, sulphate and Cl significantly modulated the activities of several enzymes tested relative to the ‘usual’ assay conditions. Consequently, we need to be alive to the possibility of many (potentially major) interactions of which we are as yet ignorant. One class of example relates to the effects of the very widespread post-translational modification on metabolic
enzyme activities.

A recent and important discovery (Fig. 4) is that a single transcriptome experiment, serving as a surrogate for fluxes through individual steps, provides a huge constraint on possible models, and predicts in a numerically tractable way and
with much improved accuracy the fluxes to exometabolites without the need for such a variable ‘biomass’ term. Other recent and related strategies that exploit modern advances in ‘omics and network biology to limit the search space in constraint-based metabolic modelling.

Fig 4. Workflow for expression-profile-constrained metabolic flux estimation

  1. Genome-scale metabolic model with gene-protein-reaction relationships
  2. Map absolute gene expression levels to reactions
  3. Maximise correlation between absolute gene expression and metabolic flux
  4. Predict fluxes to exometabolites
  5. Compare predicted with experimental fluxes to exometabolites

Drug Discovery Today

The steps in a workflow that uses constraints based on (i) metabolic network stoichiometry and chemical reaction properties (both encoded in the model) plus, and (ii) absolute (RNA-Seq) transcript expression profiles to enable the
accurate modelling of pathway and exometabolite fluxes. .

Concluding remarks – the role of metabolomics in systems pharmacology

What is becoming increasingly clear, as we recognize that to understand living organisms in health and disease we must treat them as systems, is that we must bring together our knowledge of the topologies and kinetics of metabolic networks with our knowledge of the metabolite concentrations (i.e. metabolomes) and fluxes. Because of the huge constraints imposed on metabolism by reaction stoichiometries, mass conservation and thermodynamics, comparatively few well-chosen ‘omics measurements might be needed to do this reliably (Fig. 4). Indeed, a similar approach exploiting constraints has come to the fore in denovo protein folding and interaction studies.

What this leads us to in drug discovery is the need to develop and exploit a ‘systems pharmacology’ where multiple binding targets are chosen purposely and simultaneously. Along with other measures such as phenotypic screening, and the integrating of the full suite of e-science approaches, one can anticipate considerable improvements in the rate of discovery of safe and effective drugs.

Metabolomics: the apogee of the omics trilogy
Gary J.!Patti, Oscar Yanes and Gary Siuzdak

Metabolites, the chemical entities that are transformed during metabolism, provide a functional readout of cellular biochemistry. With emerging technologies in mass spectrometry, thousands of metabolites can now be
quantitatively measured from minimal amounts of biological material, which has thereby enabled systems-level analyses. By performing global metabolite profiling, also known as untargeted metabolomics, new discoveries linking cellular pathways to biological mechanism are being revealed and are shaping our understanding of cell biology, physiology and medicine.

Metabolites are small molecules that are chemically transformed during metabolism and, as such, they provide a functional readout of cellular state. Unlike genes and proteins, the functions of which are subject to epigenetic regulation and posttranslational modifications, respectively, metabolites serve as direct signatures of biochemical activity and are therefore easier to correlate with phenotype. In this context, metabolite profiling, or metabolomics, has become a powerful approach that has been widely adopted for clinical diagnostics.

The field of metabolomics has made remarkable progress within the past decade and has implemented new tools that have offered mechanistic insights by allowing for the correlation of biochemical changes with phenotype.

In this Innovation article, we first define and differentiate between the targeted and untargeted approaches to metabolomics. We then highlight the value of untargeted metabolomics in particular and outline a guide to performing such studies. Finally, we describe selected applications of un targeted metabolomics and discuss their potential in cell biology.

  • metabolites serve as direct signatures of biochemical activity
  1. In some instances, it may be of interest to examine a defined set of metabolites by using a targeted approach.
  2. In other cases, an untargeted or global approach may be taken in which as many metabolites as possible are measured and compared between samples without bias.
  3. Ultimately, the number and chemical composition of metabolites to be studied is a defining attribute of any metabolomic experiment and shapes experimental design with respect to sample preparation and choice of instrumentation.

The targeted and untargeted workflow for LC/MS-based metabolomics.

a | In the triple quadrupole (QqQ)-based targeted metabolomic workflow, standard compounds for the metabolites of interest are first used to set up selected reaction monitoring methods. Here, optimal instrument voltages are determined and response curves are generated for absolute quantification. After the targeted methods have been established
on the basis of standard metabolites, metabolites are extracted from tissues, biofluids or cell cultures and analysed. The data output provides quantification only of those metabolites for which standard methods have been built.

b | In the untargeted metabolomic workflow, metabolites are first isolated from biological samples and subsequently analysed by liquid chromatography followed by mass spectrometry (LC/MS). After data acquisition, the results are processed by using bioinformatic software such as XCMS to perform nonlinear retention time alignment and identify peaks that are changing between the groups of samples measured. The m/z value s for the peaks of interest are searched in metabolite databases to obtain putative identifications. Putative identifications are then confirmed
by comparing tandem mass spectrometry (MS/MS) data and retention time data to that of standard compounds. The untargeted workflow is global in scope and outputs data related to comprehensive cellular metabolism.

Tumor cells respond to growth signals by the activation of protein kinases, altered gene expression and significant modifications in substrate flow and redistribution among biosynthetic pathways. This results in a proliferating phenotype
with altered cellular function. These transformed cells exhibit unique anabolic characteristics, which includes increased and preferential utilization of glucose through the non-oxidative steps of the pentose cycle for nucleic acid synthesis but limited denovo fatty acid synthesis and TCA cycle glucose oxidation. This primarily nonoxidative anabolic profile reflects an undifferentiated highly proliferative aneuploid cell phenotype and serves as a reliable metabolic biomarker to determine cell proliferation rate and the level of cell transformation/differentiation in response to drug treatment. Novel drugs effective in particular cancers exert their anti-proliferative effects by inducing significant reversions of a few specific non-oxidative anabolic pathways. Here we present evidence that cell transformation of various mechanisms is sustained by a unique
disproportional substrate distribution between the two branches of the pentose cycle for nucleic acid synthesis, glycolysis and the TCA cycle for fatty acid synthesis and glucose oxidation. This can be demonstrated by the broad labeling and unique specificity of [1,2-13C2]glucose to trace a large number of metabolites in the metabolome. Stable isotope-based dynamic metabolic profiles (SIDMAP) serve the drug discovery process by providing a powerful new tool that integrates the metabolome into a functional genomics approach to developing new drugs. It can be used in screening kinases and their metabolic targets, which can therefore be more efficiently characterized, speeding up and improving drug testing, approval and labeling processes by saving trial and error type study costs in drug testing.

Metabolomics is a rapidly evolving discipline that involves the systematic study of endogenous small molecules that characterize the metabolic pathways of biological systems. The study of metabolism at a global level has the potential to contribute significantly to biomedical research, clinical medical practice, as well as drug discovery. In this paper, we present the most up-to-date metabolite and metabolic pathway resources, and we summarize the statistical, and machine-learning tools used for the analysis of data from clinical metabolomics.

Through specific applications on cancer, diabetes, neurological and other diseases, we demonstrate how these tools can facilitate diagnosis and identification of potential biomarkers for use within disease diagnosis. Additionally, we
discuss the increasing importance of the integration of metabolomics data in drug discovery. On a case-study based on the Human Metabolome Database (HMDB) and the Chinese Natural Product Database (CNPD), we demonstrate the close relatedness of the two data sets of compounds, and we further illustrate how structural similarity with human metabolites could assist in the design of novel pharmaceuticals and the elucidation of the molecular mechanisms of medicinal plants.

Metabolites are the byproducts of metabolism, which is itself the process of converting food energy to mechanical energy
or heat. Experts believe there are at least 3,000 metabolites that are essential for normal growth and development (primary metabolites) and thousands more unidentified (around 20,000, compared to an estimated 30,000 genes and 100,000 proteins) that are not essential for growth and development (secondary metabolites) but could represent prognostic, diagnostic, and surrogate markers for a disease state and a deeper understanding of mechanisms of disease.

Metabolomics, the study of metabolism at the global level, has the potential to contribute significantly to biomedical
research, and ultimately to clinical medical practice. It is a close counterpart to the genome, the transcriptome and the proteome. Metabolomics, genomics, proteomics, and other “-omics” grew out of the Human Genome Project, a massive research effort that began in the mid-1990s and culminated in 2003 with a complete mapping of all the genes in the human body. When discussing the clinical advantages of metabolomics, scientists point to the “real-world” assessment
of patient physiology that the metabolome provides since it can be regarded as the end-point of the “-omics” cascade. Other functional genomics technologies do not necessarily predict drug effects, toxicological response, or disease states at the phenotype but merely indicate the potential cause for phenotypical response. Metabolomics can bridge this information gap. The identification and measurement of metabolite profile dynamics of host changes provides the closest link to the various phenotypic responses. Thus it is clear that the global mapping of metabolic signatures pre- and postdrug treatment is a promising approach to identify possible functional relationships between medication and medical phenotype.

Human Metabolome Database (HMDB). Focusing on quantitative, analytic, or molecular scale information about
metabolites, the enzymes and transporters associated with them, as well as disease related properties the HMDB represents the most complete bioinformatics and chemoinformatics medical information database. It contains records for
thousands of endogenous metabolites identified by literature surveys (PubMed, OMIM, OMMBID, text books), data
mining (KEGG, Metlin, BioCyc) or experimental analyses performed on urine, blood, and cerebrospinal fluid samples.
The annotation effort is aided by chemical parameter calculators and protein annotation tools originally developed for
DrugBank.

A key feature that distinguishes the HMDB from other metabolic resources is its extensive support for higher level database searching and selecting functions. More than 175 hand-drawn-zoomable, fully hyperlinked human
metabolic pathway maps can be found in HMDB and all these maps are quite specific to human metabolism and
explicitly show the subcellular compartments where specific reactions are known to take place. As an equivalent to
BLAST the HMDB contains a structure similarity search tool for chemical structures and users may sketch or
paste a SMILES string of a query compound into the Chem-Query window. Submitting the query launches a
structure similarity search tool that looks for common substructures from the query compound that match the
HMDB’s metabolite database. The wealth of information and especially the extensive linkage to metabolic diseases
to normal and abnormal metabolite concentration ranges, to mutation/SNP data and to the genes, enzymes, reactions
and pathways associated with many diseases of interest makes the HMDB one the most valuable tool in the hands
of clinical chemists, nutritionists, physicians and medical geneticists.

Metabolomics in Drug Discovery and Polypharmacology Studies

Drug molecules generally act on specific targets at the cellular level, and upon binding to the receptors, they exert
a desirable alteration of the cellular activities, regarded as the pharmaceutical effect. Current drug discovery depends
largely on ransom screening, either high-throughput screening (HTS) in vitro, or virtual screening (VS) in silico. Because
the number of available compounds is huge, several druglikeness filters are proposed to reduce the number of compounds that need to be evaluated. The ability to effectively predict if a chemical compound is “drug-like” or “nondruglike” is, thus, a valuable tool in the design, optimization, and selection of drug candidates for development. Druglikeness is a general descriptor of the potential of a small molecule to become a drug. It is not a unified descriptor
but a global property of a compound processing many specific characteristics such as good solubility, membrane
permeability, half-life, and having a pharmacophore pattern to interact specifically with a target protein. These
characteristics can be reflected as molecular descriptors such as molecular weight, log P, the number of hydrogen bond
donors, the number of hydrogen-bond acceptors, the number of rotatable bonds, the number of rigid bonds, the
number of rings in a molecule, and so forth.

Metabolomics for the Study of Polypharmacology of Natural Compounds

Internationally, there is a growing and sustained interest from both pharmaceutical companies and public in medicine
from natural sources. For the public, natural medicine represent a holistic approach to disease treatment, with
potentially less side effects than conventional medicine. For the pharmaceutical companies, bioactive natural products
constitute attractive drug leads, as they have been optimized in a long-term natural selection process for optimal interaction with biomolecules. To promote the ecological survival of plants, structures of secondary products have evolved to interact with molecular targets affecting the cells, tissues and physiological functions in competing microorganisms,
plants, and animals. In this, respect, some plant secondary products may exert their action by resembling endogenous
metabolites, ligands, hormones, signal transduction molecules, or neurotransmitters and thus have beneficial
effects on humans.

Future Perspectives

Metabolomics, the study of metabolism at the global level, is moving to exciting directions.With the development ofmore
sensitive and advanced instrumentation and computational tools for data interpretation in the physiological context,
metabolomics have the potential to impact our understanding of molecular mechanisms of diseases. A state-of-theart
metabolomics study requires knowledge in many areas and especially at the interface of chemistry, biology, and
computer science. High-quality samples, improvements in automated metabolite identification, complete coverage of
the human metabolome, establishment of spectral databases of metabolites and associated biochemical identities, innovative experimental designs to best address a hypothesis, as well as novel computational tools to handle metabolomics data are critical hurdles that must be overcome to drive the inclusion of metabolomics in all steps of drug discovery and drug development. The examples presented above demonstrated that metabolite profiles reflect both environmental and genetic influences in patients and reveal new links between metabolites and diseases providing needed prognostic,diagnostic, and surrogate biomarkers. The integration of these signatures with other omic technologies is of utmost importance to characterize the entire spectrum of malignant phenotype.

Twitter is Becoming a Powerful Tool in Science and Medicine

 Curator: Stephen J. Williams, Ph.D.

Article ID #159: Twitter is Becoming a Powerful Tool in Science and Medicine. Published on 11/6/2014

WordCloud Image Produced by Adam Tubman

Updated 4/2016

Life-cycle of Science 2

A recent Science article (Who are the science stars of Twitter?; Sept. 19, 2014) reported the top 50 scientists followed on Twitter. However, the article tended to focus on the use of Twitter as a means to develop popularity, a sort of “Science Kardashian” as they coined it. So the writers at Science developed a “Kardashian Index (K-Index) to determine scientists following and popularity on Twitter.

Now as much buzz Kim Kardashian or a Perez Hilton get on social media, their purpose is solely for entertainment and publicity purposes, the Science sort of fell flat in that it focused mainly on the use of Twitter as a metric for either promotional or public outreach purposes. A notable scientist was mentioned in the article, using Twitter feed to gauge the receptiveness of his presentation. In addition, relying on Twitter for effective public discourse of science is problematic as:

  • Twitter feeds are rapidly updated and older feeds quickly get buried within the “Twittersphere” = LIMITED EXPOSURE TIMEFRAME
  • Short feeds may not provide the access to appropriate and understandable scientific information (The Science Communication Trap) which is explained in The Art of Communicating Science: traps, tips and tasks for the modern-day scientist. “The challenge of clearly communicating the intended scientific message to the public is not insurmountable but requires an understanding of what works and what does not work.” – from Heidi Roop, G.-Martinez-Mendez and K. Mills

However, as highlighted below, Twitter, and other social media platforms are being used in creative ways to enhance the research, medical, and bio investment collaborative, beyond a simple news-feed.  And the power of Twitter can be attributed to two simple features

  1. Ability to organize – through use of the hashtag (#) and handle (@), Twitter assists in the very important task of organizing, indexing, and ANNOTATING content and conversations. A very great article on Why the Hashtag in Probably the Most Powerful Tool on Twitter by Vanessa Doctor explains how hashtags and # search may be as popular as standard web-based browser search. Thorough annotation is crucial for any curation process, which are usually in the form of database tags or keywords. The use of # and @ allows curators to quickly find, index and relate disparate databases to link annotated information together. The discipline of scientific curation requires annotation to assist in the digital preservation, organization, indexing, and access of data and scientific & medical literature. For a description of scientific curation methodologies please see the following links:

Please read the following articles on CURATION

The Methodology of Curation for Scientific Research Findings

Power of Analogy: Curation in Music, Music Critique as a Curation and Curation of Medical Research Findings – A Comparison

Science and Curation: The New Practice of Web 2.0

  1. Information Analytics

Multiple analytic software packages have been made available to analyze information surrounding Twitter feeds, including Twitter feeds from #chat channels one can set up to cover a meeting, product launch etc.. Some of these tools include:

Twitter Analytics – measures metrics surrounding Tweets including retweets, impressions, engagement, follow rate, …

Twitter Analytics – Hashtags.org – determine most impactful # for your Tweets For example, meeting coverage of bioinvestment conferences or startup presentations using #startup generates automatic retweeting by Startup tweetbot @StartupTweetSF.

 

  1. Tweet Sentiment Analytics

Examples of Twitter Use

A. Scientific Meeting Coverage

In a paper entitled Twitter Use at a Family Medicine Conference: Analyzing #STFM13 authors Ranit Mishori, MD, Frendan Levy, MD, and Benjamin Donvan analyzed the public tweets from the 2013 Society of Teachers of Family Medicine (STFM) conference bearing the meeting-specific hashtag #STFM13. Thirteen percent of conference attendees (181 users) used the #STFM13 to share their thoughts on the meeting (1,818 total tweets) showing a desire for social media interaction at conferences but suggesting growth potential in this area. As we have also seen, the heaviest volume of conference-tweets originated from a small number of Twitter users however most tweets were related to session content.

However, as the authors note, although it is easy to measure common metrics such as number of tweets and retweets, determining quality of engagement from tweets would be important for gauging the value of Twitter-based social-media coverage of medical conferences.

Thea authors compared their results with similar analytics generated by the HealthCare Hashtag Project, a project and database of medically-related hashtag use, coordinated and maintained by the company Symplur.  Symplur’s database includes medical and scientific conference Twitter coverage but also Twitter usuage related to patient care. In this case the database was used to compare meeting tweets and hashtag use with the 2012 STFM conference.

These are some of the published journal articles that have employed Symplur (www.symplur.com) data in their research of Twitter usage in medical conferences.

B. Twitter Usage for Patient Care and Engagement

Although the desire of patients to use and interact with their physicians over social media is increasing, along with increasing health-related social media platforms and applications, there are certain obstacles to patient-health provider social media interaction, including lack of regulatory framework as well as database and security issues. Some of the successes and issues of social media and healthcare are discussed in the post Can Mobile Health Apps Improve Oral-Chemotherapy Adherence? The Benefit of Gamification.

However there is also a concern if social media truly engages the patient and improves patient education. In a study of Twitter communications by breast cancer patients Tweeting about breast cancer, authors noticed Tweeting was a singular event. The majority of tweets did not promote any specific preventive behavior. The authors concluded “Twitter is being used mostly as a one-way communication tool.” (Using Twitter for breast cancer prevention: an analysis of breast cancer awareness month. Thackeray R1, Burton SH, Giraud-Carrier C, Rollins S, Draper CR. BMC Cancer. 2013;13:508).

In addition a new poll by Harris Interactive and HealthDay shows one third of patients want some mobile interaction with their physicians.

Some papers cited in Symplur’s HealthCare Hashtag Project database on patient use of Twitter include:

C. Twitter Use in Pharmacovigilance to Monitor Adverse Events

Pharmacovigilance is the systematic detection, reporting, collecting, and monitoring of adverse events pre- and post-market of a therapeutic intervention (drug, device, modality e.g.). In a Cutting Edge Information Study, 56% of pharma companies databases are an adverse event channel and more companies are turning to social media to track adverse events (in Pharmacovigilance Teams Turn to Technology for Adverse Event Reporting Needs). In addition there have been many reports (see Digital Drug Safety Surveillance: Monitoring Pharmaceutical Products in Twitter) that show patients are frequently tweeting about their adverse events.

There have been concerns with using Twitter and social media to monitor for adverse events. For example FDA funded a study where a team of researchers from Harvard Medical School and other academic centers examined more than 60,000 tweets, of which 4,401 were manually categorized as resembling adverse events and compared with the FDA pharmacovigilance databases. Problems associated with such social media strategy were inability to obtain extra, needed information from patients and difficulty in separating the relevant Tweets from irrelevant chatter.  The UK has launched a similar program called WEB-RADR to determine if monitoring #drug_reaction could be useful for monitoring adverse events. Many researchers have found the adverse-event related tweets “noisy” due to varied language but had noticed many people do understand some principles of causation including when adverse event subsides after discontinuing the drug.

However Dr. Clark Freifeld, Ph.D., from Boston University and founder of the startup Epidemico, feels his company has the algorithms that can separate out the true adverse events from the junk. According to their web site, their algorithm has high accuracy when compared to the FDA database. Dr. Freifeld admits that Twitter use for pharmacovigilance purposes is probably a starting point for further follow-up, as each patient needs to fill out the four-page forms required for data entry into the FDA database.

Imaging-guided cancer treatment

Imaging-guided cancer treatment

Writer & reporter: Dror Nir, PhD

It is estimated that the medical imaging market will exceed $30 billion in 2014 (FierceMedicalImaging). To put this amount in perspective; the global pharmaceutical market size for the same year is expected to be ~$1 trillion (IMS) while the global health care spending as a percentage of Gross Domestic Product (GDP) will average 10.5% globally in 2014 (Deloitte); it will reach ~$3 trillion in the USA.

Recent technology-advances, mainly miniaturization and improvement in electronic-processing components is driving increased introduction of innovative medical-imaging devices into critical nodes of major-diseases’ management pathways. Consequently, in contrast to it’s very small contribution to global health costs, medical imaging bears outstanding potential to reduce the future growth in spending on major segments in this market mainly: Drugs development and regulation (e.g. companion diagnostics and imaging surrogate markers); Disease management (e.g. non-invasive diagnosis, guided treatment and non-invasive follow-ups); and Monitoring aging-population (e.g. Imaging-based domestic sensors).

In; The Role of Medical Imaging in Personalized Medicine I discussed in length the role medical imaging assumes in drugs development.  Integrating imaging into drug development processes, specifically at the early stages of drug discovery, as well as for monitoring drug delivery and the response of targeted processes to the therapy is a growing trend. A nice (and short) review highlighting the processes, opportunities, and challenges of medical imaging in new drug development is: Medical imaging in new drug clinical development.

The following is dedicated to the role of imaging in guiding treatment.

Precise treatment is a major pillar of modern medicine. An important aspect to enable accurate administration of treatment is complementing the accurate identification of the organ location that needs to be treated with a system and methods that ensure application of treatment only, or mainly to, that location. Imaging is off-course, a major component in such composite systems. Amongst the available solution, functional-imaging modalities are gaining traction. Specifically, molecular imaging (e.g. PET, MRS) allows the visual representation, characterization, and quantification of biological processes at the cellular and subcellular levels within intact living organisms. In oncology, it can be used to depict the abnormal molecules as well as the aberrant interactions of altered molecules on which cancers depend. Being able to detect such fundamental finger-prints of cancer is key to improved matching between drugs-based treatment and disease. Moreover, imaging-based quantified monitoring of changes in tumor metabolism and its microenvironment could provide real-time non-invasive tool to predict the evolution and progression of primary tumors, as well as the development of tumor metastases.

A recent review-paper: Image-guided interventional therapy for cancer with radiotherapeutic nanoparticles nicely illustrates the role of imaging in treatment guidance through a comprehensive discussion of; Image-guided radiotherapeutic using intravenous nanoparticles for the delivery of localized radiation to solid cancer tumors.

 Graphical abstract

 Abstract

One of the major limitations of current cancer therapy is the inability to deliver tumoricidal agents throughout the entire tumor mass using traditional intravenous administration. Nanoparticles carrying beta-emitting therapeutic radionuclides [DN: radioactive isotops that emits electrons as part of the decay process a list of β-emitting radionuclides used in radiotherapeutic nanoparticle preparation is given in table1 of this paper.) that are delivered using advanced image-guidance have significant potential to improve solid tumor therapy. The use of image-guidance in combination with nanoparticle carriers can improve the delivery of localized radiation to tumors. Nanoparticles labeled with certain beta-emitting radionuclides are intrinsically theranostic agents that can provide information regarding distribution and regional dosimetry within the tumor and the body. Image-guided thermal therapy results in increased uptake of intravenous nanoparticles within tumors, improving therapy. In addition, nanoparticles are ideal carriers for direct intratumoral infusion of beta-emitting radionuclides by convection enhanced delivery, permitting the delivery of localized therapeutic radiation without the requirement of the radionuclide exiting from the nanoparticle. With this approach, very high doses of radiation can be delivered to solid tumors while sparing normal organs. Recent technological developments in image-guidance, convection enhanced delivery and newly developed nanoparticles carrying beta-emitting radionuclides will be reviewed. Examples will be shown describing how this new approach has promise for the treatment of brain, head and neck, and other types of solid tumors.

The challenges this review discusses

  • intravenously administered drugs are inhibited in their intratumoral penetration by high interstitial pressures which prevent diffusion of drugs from the blood circulation into the tumor tissue [1–5].
  • relatively rapid clearance of intravenously administered drugs from the blood circulation by kidneys and liver.
  • drugs that do reach the solid tumor by diffusion are inhomogeneously distributed at the micro-scale – This cannot be overcome by simply administering larger systemic doses as toxicity to normal organs is generally the dose limiting factor.
  • even nanoparticulate drugs have poor penetration from the vascular compartment into the tumor and the nanoparticles that do penetrate are most often heterogeneously distributed

How imaging could mitigate the above mentioned challenges

  • The inclusion of an imaging probe during drug development can aid in determining the clearance kinetics and tissue distribution of the drug non-invasively. Such probe can also be used to determine the likelihood of the drug reaching the tumor and to what extent.

Note: Drugs that have increased accumulation within the targeted site are likely to be more effective as compared with others. In that respect, Nanoparticle-based drugs have an additional advantage over free drugs with their potential to be multifunctional carriers capable of carrying both therapeutic and diagnostic imaging probes (theranostic) in the same nanocarrier. These multifunctional nanoparticles can serve as theranostic agents and facilitate personalized treatment planning.

  • Imaging can also be used for localization of the tumor to improve the placement of a catheter or external device within tumors to cause cell death through thermal ablation or oxidative stress secondary to reactive oxygen species.

See the example of Vintfolide in The Role of Medical Imaging in Personalized Medicine

vinta

Note: Image guided thermal ablation methods include radiofrequency (RF) ablation, microwave ablation or high intensity focused ultrasound (HIFU). Photodynamic therapy methods using external light devices to activate photosensitizing agents can also be used to treat superficial tumors or deeper tumors when used with endoscopic catheters.

  • Quality control during and post treatment

For example: The use of high intensity focused ultrasound (HIFU) combined with nanoparticle therapeutics: HIFU is applied to improve drug delivery and to trigger drug release from nanoparticles. Gas-bubbles are playing the role of the drug’s nano-carrier. These are used both to increase the drug transport into the cell and as ultrasound-imaging contrast material. The ultrasound is also used for processes of drug-release and ablation.

 HIFU

Additional example; Multifunctional nanoparticles for tracking CED (convection enhanced delivery)  distribution within tumors: Nanoparticle that could serve as a carrier not only for the therapeutic radionuclides but simultaneously also for a therapeutic drug and 4 different types of imaging contrast agents including an MRI contrast agent, PET and SPECT nuclear diagnostic imaging agents and optical contrast agents as shown below. The ability to perform multiple types of imaging on the same nanoparticles will allow studies investigating the distribution and retention of nanoparticles initially in vivo using non-invasive imaging and later at the histological level using optical imaging.

 multi

Conclusions

Image-guided radiotherapeutic nanoparticles have significant potential for solid tumor cancer therapy. The current success of this therapy in animals is most likely due to the improved accumulation, retention and dispersion of nanoparticles within solid tumor following image-guided therapies as well as the micro-field of the β-particle which reduces the requirement of perfectly homogeneous tumor coverage. It is also possible that the intratumoral distribution of nanoparticles may benefit from their uptake by intratumoral macrophages although more research is required to determine the importance of this aspect of intratumoral radionuclide nanoparticle therapy. This new approach to cancer therapy is a fertile ground for many new technological developments as well as for new understandings in the basic biology of cancer therapy. The clinical success of this approach will depend on progress in many areas of interdisciplinary research including imaging technology, nanoparticle technology, computer and robot assisted image-guided application of therapies, radiation physics and oncology. Close collaboration of a wide variety of scientists and physicians including chemists, nanotechnologists, drug delivery experts, radiation physicists, robotics and software experts, toxicologists, surgeons, imaging physicians, and oncologists will best facilitate the implementation of this novel approach to the treatment of cancer in the clinical environment. Image-guided nanoparticle therapies including those with β-emission radionuclide nanoparticles have excellent promise to significantly impact clinical cancer therapy and advance the field of drug delivery.

Dompe’ Receives FDA orphan drug designation for rhNGF in the treatment of Neurotrophic Keratitis (NK).

Reporter: Stephen J Williams, PhD

 

The U.S. FDA granted Dompe’ an orphan drug designation for rhNGF (recombinant human nerve growth factor) in the treatment of Neurotrophic Keratitis (NK).

Neurotrophic Keratitis (NK) is a rare, degenerative corneal disease caused by an impairment of corneal innervation (the distribution or supply of nerves), leading to a decrease or absence of corneal sensation and dysfunction of the corneal epithelium and abnormal corneal epithelial healing. The development of persistent epithelial defects or corneal ulcers can result in vision loss.

Severe NK is consistently recognized by clinicians as a serious condition lacking a highly effective treatment option.

The epidemiology of NK has not been well-defined. The estimated prevalence of patients with moderate-to-severe NK (stage 2-3) is less than 1 person in 5,000 globally.

Clinical trials in the U.S. are expected to begin in the next few months in leading research centers.

Dompé will be present at the American Association of Ophthalmology Annual meeting (Chicago, October 18-21). Currently, the enrollment is ongoing for the company’s Phase II trial with rhNGF in the treatment of NK.
Background – Dompé and its R&D

  • Dompé is a leading Italian biopharmaceutical company (with headquarters in Milan) committed to the development of innovative treatment solutions for rare, often orphan, diseases that have a high social impact, in areas where unmet treatment needs still exist.
  • The Company focuses its R&D activities in diabetes, ophthalmology, oncology and organ transplants.
  • The R&D activities are carried out in the Dompé biotech plant located in L’Aquila (Abruzzo), which has an internationally recognized expertise in the field of rare diseases.  
  • This year (2014), Dompé opened an office in New York, staffed with scientists and R&D teams in order to carry out and coordinate the scientific activities in the U.S.

 

Dompé commitment in ophthalmology – rhNGF

  • In ophthalmology, Dompé is promoting the research and development of Nerve Growth Factor (NGF), a soluble protein that stimulates the growth, maintenance and survival of neurons, whose discovery led to Prof. Rita Levi Montalcini being awarded the Nobel Prize in 1986.
  • Recombinant human Nerve Growth Factor (rhNGF) has been studied and produced exclusively at Dompé’s production site in L’Aquila, Italy, and is undergoing an international Phase II trial, called “REPARO”, to evaluate its efficacy and safety in the treatment of Neurotrophic Keratitis, a rare orphan disease. The trial is being conducted in 39 centers and nine European countries.

The medicine recently has been designated an orphan drug for the treatment of Retinitis Pigmentosa (RP), a severe, genetic rare disease that can lead to blindness for which there is currently no treatment available. A clinical trial in the EU, involving patients with RP, started in the first quarter of 2014 with the enrolment of the first patient.

Scientific Curation Fostering Expert Networks and Open Innovation: Lessons from Clive Thompson

Life-cycle of Science 2

 

 

 

 

 

 

 

 

 

 

 

Curators and Writer: Stephen J. Williams, Ph.D. with input from Curators Larry H. Bernstein, MD, FCAP, Dr. Justin D. Pearlman, MD, PhD, FACC and Dr. Aviva Lev-Ari, PhD, RN

(this discussion is in a three part series including:

Using Scientific Content Curation as a Method for Validation and Biocuration

Using Scientific Content Curation as a Method for Open Innovation)

 

Every month I get my Wired Magazine (yes in hard print, I still like to turn pages manually plus I don’t mind if I get grease or wing sauce on my magazine rather than on my e-reader) but I always love reading articles written by Clive Thompson. He has a certain flair for understanding the techno world we live in and the human/technology interaction, writing about interesting ways in which we almost inadvertently integrate new technologies into our day-to-day living, generating new entrepreneurship, new value.   He also writes extensively about tech and entrepreneurship.

October 2013 Wired article by Clive Thompson, entitled “How Successful Networks Nurture Good Ideas: Thinking Out Loud”, describes how the voluminous writings, postings, tweets, and sharing on social media is fostering connections between people and ideas which, previously, had not existed. The article was generated from Clive Thompson’s book Smarter Than you Think: How Technology is Changing Our Minds for the Better.Tom Peters also commented about the article in his blog (see here).

Clive gives a wonderful example of Ory Okolloh, a young Kenyan-born law student who, after becoming frustrated with the lack of coverage of problems back home, started a blog about Kenyan politics. Her blog not only got interest from movie producers who were documenting female bloggers but also gained the interest of fellow Kenyans who, during the upheaval after the 2007 Kenyan elections, helped Ory to develop a Google map for reporting of violence (http://www.ushahidi.com/, which eventually became a global organization using open-source technology to affect crises-management. There are a multitude of examples how networks and the conversations within these circles are fostering new ideas. As Clive states in the article:

 

Our ideas are PRODUCTS OF OUR ENVIRONMENT.

They are influenced by the conversations around us.

However the article got me thinking of how Science 2.0 and the internet is changing how scientists contribute, share, and make connections to produce new and transformative ideas.

But HOW MUCH Knowledge is OUT THERE?

 

Clive’s article listed some amazing facts about the mountains of posts, tweets, words etc. out on the internet EVERY DAY, all of which exemplifies the problem:

  • 154.6 billion EMAILS per DAY
  • 400 million TWEETS per DAY
  • 1 million BLOG POSTS (including this one) per DAY
  • 2 million COMMENTS on WordPress per DAY
  • 16 million WORDS on Facebook per DAY
  • TOTAL 52 TRILLION WORDS per DAY

As he estimates this would be 520 million books per DAY (book with average 100,000 words).

A LOT of INFO. But as he suggests it is not the volume but how we create and share this information which is critical as the science fiction writer Theodore Sturgeon noted “Ninety percent of everything is crap” AKA Sturgeon’s Law.

 

Internet live stats show how congested the internet is each day (http://www.internetlivestats.com/). Needless to say Clive’s numbers are a bit off. As of the writing of this article:

 

  • 2.9 billion internet users
  • 981 million websites (only 25,000 hacked today)
  • 128 billion emails
  • 385 million Tweets
  • > 2.7 million BLOG posts today (including this one)

 

The Good, The Bad, and the Ugly of the Scientific Internet (The Wild West?)

 

So how many science blogs are out there? Well back in 2008 “grrlscientistasked this question and turned up a total of 19,881 blogs however most were “pseudoscience” blogs, not written by Ph.D or MD level scientists. A deeper search on Technorati using the search term “scientist PhD” turned up about 2,000 written by trained scientists.

So granted, there is a lot of

goodbadugly

 

              ….. when it comes to scientific information on the internet!

 

 

 

 

 

I had recently re-posted, on this site, a great example of how bad science and medicine can get propagated throughout the internet:

http://pharmaceuticalintelligence.com/2014/06/17/the-gonzalez-protocol-worse-than-useless-for-pancreatic-cancer/

 

and in a Nature Report:Stem cells: Taking a stand against pseudoscience

http://www.nature.com/news/stem-cells-taking-a-stand-against-pseudoscience-1.15408

Drs.Elena Cattaneo and Gilberto Corbellini document their long, hard fight against false and invalidated medical claims made by some “clinicians” about the utility and medical benefits of certain stem-cell therapies, sacrificing their time to debunk medical pseudoscience.

 

Using Curation and Science 2.0 to build Trusted, Expert Networks of Scientists and Clinicians

 

Establishing networks of trusted colleagues has been a cornerstone of the scientific discourse for centuries. For example, in the mid-1640s, the Royal Society began as:

 

“a meeting of natural philosophers to discuss promoting knowledge of the

natural world through observation and experiment”, i.e. science.

The Society met weekly to witness experiments and discuss what we

would now call scientific topics. The first Curator of Experiments

was Robert Hooke.”

 

from The History of the Royal Society

 

Royal Society CoatofArms

 

 

 

 

 

 

The Royal Society of London for Improving Natural Knowledge.

(Although one wonders why they met “in-cognito”)

Indeed as discussed in “Science 2.0/Brainstorming” by the originators of OpenWetWare, an open-source science-notebook software designed to foster open-innovation, the new search and aggregation tools are making it easier to find, contribute, and share information to interested individuals. This paradigm is the basis for the shift from Science 1.0 to Science 2.0. Science 2.0 is attempting to remedy current drawbacks which are hindering rapid and open scientific collaboration and discourse including:

  • Slow time frame of current publishing methods: reviews can take years to fashion leading to outdated material
  • Level of information dissemination is currently one dimensional: peer-review, highly polished work, conferences
  • Current publishing does not encourage open feedback and review
  • Published articles edited for print do not take advantage of new web-based features including tagging, search-engine features, interactive multimedia, no hyperlinks
  • Published data and methodology incomplete
  • Published data not available in formats which can be readably accessible across platforms: gene lists are now mandated to be supplied as files however other data does not have to be supplied in file format

(put in here a brief blurb of summary of problems and why curation could help)

 

Curation in the Sciences: View from Scientific Content Curators Larry H. Bernstein, MD, FCAP, Dr. Justin D. Pearlman, MD, PhD, FACC and Dr. Aviva Lev-Ari, PhD, RN

Curation is an active filtering of the web’s  and peer reviewed literature found by such means – immense amount of relevant and irrelevant content. As a result content may be disruptive. However, in doing good curation, one does more than simply assign value by presentation of creative work in any category. Great curators comment and share experience across content, authors and themes. Great curators may see patterns others don’t, or may challenge or debate complex and apparently conflicting points of view.  Answers to specifically focused questions comes from the hard work of many in laboratory settings creatively establishing answers to definitive questions, each a part of the larger knowledge-base of reference. There are those rare “Einstein’s” who imagine a whole universe, unlike the three blind men of the Sufi tale.  One held the tail, the other the trunk, the other the ear, and they all said this is an elephant!
In my reading, I learn that the optimal ratio of curation to creation may be as high as 90% curation to 10% creation. Creating content is expensive. Curation, by comparison, is much less expensive.

– Larry H. Bernstein, MD, FCAP

Curation is Uniquely Distinguished by the Historical Exploratory Ties that Bind –Larry H. Bernstein, MD, FCAP

The explosion of information by numerous media, hardcopy and electronic, written and video, has created difficulties tracking topics and tying together relevant but separated discoveries, ideas, and potential applications. Some methods to help assimilate diverse sources of knowledge include a content expert preparing a textbook summary, a panel of experts leading a discussion or think tank, and conventions moderating presentations by researchers. Each of those methods has value and an audience, but they also have limitations, particularly with respect to timeliness and pushing the edge. In the electronic data age, there is a need for further innovation, to make synthesis, stimulating associations, synergy and contrasts available to audiences in a more timely and less formal manner. Hence the birth of curation. Key components of curation include expert identification of data, ideas and innovations of interest, expert interpretation of the original research results, integration with context, digesting, highlighting, correlating and presenting in novel light.

Justin D Pearlman, MD, PhD, FACC from The Voice of Content Consultant on The  Methodology of Curation in Cardiovascular Original Research: Cases in Methodology Design for Content Co-Curation The Art of Scientific & Medical Curation

 

In Power of Analogy: Curation in Music, Music Critique as a Curation and Curation of Medical Research Findings – A Comparison, Drs. Larry Bernstein and Aviva Lev-Ari likens the medical and scientific curation process to curation of musical works into a thematic program:

… leading to new, curated, and collaborative works by networks of experts to generate (in this case) ebooks on most significant trends and interpretations of scientific knowledge as relates to medical practice.

 

In Summary: How Scientific Content Curation Can Help

 

Given the aforementioned problems of:

        I.            the complex and rapid deluge of scientific information

      II.            the need for a collaborative, open environment to produce transformative innovation

    III.            need for alternative ways to disseminate scientific findings

CURATION MAY OFFER SOLUTIONS

        I.            Curation exists beyond the review: curation decreases time for assessment of current trends adding multiple insights, analyses WITH an underlying METHODOLOGY (discussed below) while NOT acting as mere reiteration, regurgitation

 

      II.            Curation providing insights from WHOLE scientific community on multiple WEB 2.0 platforms

 

    III.            Curation makes use of new computational and Web-based tools to provide interoperability of data, reporting of findings (shown in Examples below)

 

Therefore a discussion is given on methodologies, definitions of best practices, and tools developed to assist the content curation community in this endeavor.

Methodology in Scientific Content Curation as Envisioned by Aviva lev-Ari, PhD, RN

 

At Leaders in Pharmaceutical Business Intelligence, site owner and chief editor Aviva lev-Ari, PhD, RN has been developing a strategy “for the facilitation of Global access to Biomedical knowledge rather than the access to sheer search results on Scientific subject matters in the Life Sciences and Medicine”. According to Aviva, “for the methodology to attain this complex goal it is to be dealing with popularization of ORIGINAL Scientific Research via Content Curation of Scientific Research Results by Experts, Authors, Writers using the critical thinking process of expert interpretation of the original research results.” The following post:

Cardiovascular Original Research: Cases in Methodology Design for Content Curation and Co-Curation

 

http://pharmaceuticalintelligence.com/2013/07/29/cardiovascular-original-research-cases-in-methodology-design-for-content-curation-and-co-curation/

demonstrate two examples how content co-curation attempts to achieve this aim and develop networks of scientist and clinician curators to aid in the active discussion of scientific and medical findings, and use scientific content curation as a means for critique offering a “new architecture for knowledge”. Indeed, popular search engines such as Google, Yahoo, or even scientific search engines such as NCBI’s PubMed and the OVID search engine rely on keywords and Boolean algorithms …

which has created a need for more context-driven scientific search and discourse.

In Science and Curation: the New Practice of Web 2.0, Célya Gruson-Daniel (@HackYourPhd) states:

To address this need, human intermediaries, empowered by the participatory wave of web 2.0, naturally started narrowing down the information and providing an angle of analysis and some context. They are bloggers, regular Internet users or community managers – a new type of profession dedicated to the web 2.0. A new use of the web has emerged, through which the information, once produced, is collectively spread and filtered by Internet users who create hierarchies of information.

.. where Célya considers curation an essential practice to manage open science and this new style of research.

As mentioned above in her article, Dr. Lev-Ari represents two examples of how content curation expanded thought, discussion, and eventually new ideas.

  1. Curator edifies content through analytic process = NEW form of writing and organizations leading to new interconnections of ideas = NEW INSIGHTS

i)        Evidence: curation methodology leading to new insights for biomarkers

 

  1. Same as #1 but multiple players (experts) each bringing unique insights, perspectives, skills yielding new research = NEW LINE of CRITICAL THINKING

ii)      Evidence: co-curation methodology among cardiovascular experts leading to cardiovascular series ebooks

Life-cycle of Science 2

The Life Cycle of Science 2.0. Due to Web 2.0, new paradigms of scientific collaboration are rapidly emerging.  Originally, scientific discovery were performed by individual laboratories or “scientific silos” where the main method of communication was peer-reviewed publication, meeting presentation, and ultimately news outlets and multimedia. In this digital era, data was organized for literature search and biocurated databases. In an era of social media, Web 2.0, a group of scientifically and medically trained “curators” organize the piles of data of digitally generated data and fit data into an organizational structure which can be shared, communicated, and analyzed in a holistic approach, launching new ideas due to changes in organization structure of data and data analytics.

 

The result, in this case, is a collaborative written work above the scope of the review. Currently review articles are written by experts in the field and summarize the state of a research are. However, using collaborative, trusted networks of experts, the result is a real-time synopsis and analysis of the field with the goal in mind to

INCREASE THE SCIENTIFIC CURRENCY.

For detailed description of methodology please see Cardiovascular Original Research: Cases in Methodology Design for Content Co-Curation The Art of Scientific & Medical Curation

 

In her paper, Curating e-Science Data, Maureen Pennock, from The British Library, emphasized the importance of using a diligent, validated, and reproducible, and cost-effective methodology for curation by e-science communities over the ‘Grid:

“The digital data deluge will have profound repercussions for the infrastructure of research and beyond. Data from a wide variety of new and existing sources will need to be annotated with metadata, then archived and curated so that both the data and the programmes used to transform the data can be reproduced for use in the future. The data represent a new foundation for new research, science, knowledge and discovery”

— JISC Senior Management Briefing Paper, The Data Deluge (2004)

 

As she states proper data and content curation is important for:

  • Post-analysis
  • Data and research result reuse for new research
  • Validation
  • Preservation of data in newer formats to prolong life-cycle of research results

However she laments the lack of

  • Funding for such efforts
  • Training
  • Organizational support
  • Monitoring
  • Established procedures

 

Tatiana Aders wrote a nice article based on an interview with Microsoft’s Robert Scoble, where he emphasized the need for curation in a world where “Twitter is the replacement of the Associated Press Wire Machine” and new technologic platforms are knocking out old platforms at a rapid pace. In addition he notes that curation is also a social art form where primary concerns are to understand an audience and a niche.

Indeed, part of the reason the need for curation is unmet, as writes Mark Carrigan, is the lack of appreciation by academics of the utility of tools such as Pinterest, Storify, and Pearl Trees to effectively communicate and build collaborative networks.

And teacher Nancy White, in her article Understanding Content Curation on her blog Innovations in Education, shows examples of how curation in an educational tool for students and teachers by demonstrating students need to CONTEXTUALIZE what the collect to add enhanced value, using higher mental processes such as:

  • Knowledge
  • Comprehension
  • Application
  • Analysis
  • Synthesis
  • Evaluation

University of Massachusetts Medical School has aggregated some useful curation tools at http://esciencelibrary.umassmed.edu/data_curation

Although many tools are related to biocuration and building databases but the common idea is curating data with indexing, analyses, and contextual value to provide for an audience to generate NETWORKS OF NEW IDEAS.

See here for a curation of how networks fosters knowledge, by Erika Harrison on ScoopIt

(http://www.scoop.it/t/mobilizing-knowledge-through-complex-networks)

 

“Nowadays, any organization should employ network scientists/analysts who are able to map and analyze complex systems that are of importance to the organization (e.g. the organization itself, its activities, a country’s economic activities, transportation networks, research networks).”

Creating Content Curation Communities: Breaking Down the Silos!

 

An article by Dr. Dana Rotman “Facilitating Scientific Collaborations Through Content Curation Communities” highlights how scientific information resources, traditionally created and maintained by paid professionals, are being crowdsourced to professionals and nonprofessionals in which she termed “content curation communities”, consisting of professionals and nonprofessional volunteers who create, curate, and maintain the various scientific database tools we use such as Encyclopedia of Life, ChemSpider (for Slideshare see here), biowikipedia etc. Although very useful and openly available, these projects create their own challenges such as

  • information integration (various types of data and formats)
  • social integration (marginalized by scientific communities, no funding, no recognition)

The authors set forth some ways to overcome these challenges of the content curation community including:

  1. standardization in practices
  2. visualization to document contributions
  3. emphasizing role of information professionals in content curation communities
  4. maintaining quality control to increase respectability
  5. recognizing participation to professional communities
  6. proposing funding/national meeting – Data Intensive Collaboration in Science and Engineering Workshop

Indeed, the movement of Science 2.0 from Science 1.0 had originated because these “silos” had frustrated many scientists, resulting in changes in the area of publishing (Open Access) but also communication of protocols (online protocol sites and notebooks like OpenWetWare and BioProtocols Online) and data and material registries (CGAP and tumor banks). Some examples are given below.

Open Science Case Studies in Curation

1. Open Science Project from Digital Curation Center

This project looked at what motivates researchers to work in an open manner with regard to their data, results and protocols, and whether advantages are delivered by working in this way.

The case studies consider the benefits and barriers to using ‘open science’ methods, and were carried out between November 2009 and April 2010 and published in the report Open to All? Case studies of openness in research. The Appendices to the main report (pdf) include a literature review, a framework for characterizing openness, a list of examples, and the interview schedule and topics. Some of the case study participants kindly agreed to us publishing the transcripts. This zip archive contains transcripts of interviews with researchers in astronomy, bioinformatics, chemistry, and language technology.

9. Some ongoing biomedical knowledge (curation) projects at ISI

IICurate
This project is concerned with developing a curation and documentation system for information integration in collaboration with the II Group at ISI as part of the BIRN.

BioScholar
It’s primary purpose is to provide software for experimental biomedical scientists that would permit a single scientific worker (at the level of a graduate student or postdoctoral worker) to design, construct and manage a shared knowledge repository for a research group derived on a local store of PDF files. This project is funded by NIGMS from 2008-2012 ( RO1-GM083871).

10. Tools useful for scientific content curation

 

Research Analytic and Curation Tools from University of Queensland

 

Thomson Reuters information curation services for pharma industry

 

Microblogs as a way to communicate information about HPV infection among clinicians and patients; use of Chinese microblog SinaWeibo as a communication tool

 

VIVO for scientific communities– In order to connect this information about research activities across institutions and make it available to others, taking into account smaller players in the research landscape and addressing their need for specific information (for example, by proving non-conventional research objects), the open source software VIVO that provides research information as linked open data (LOD) is used in many countries.  So-called VIVO harvesters collect research information that is freely available on the web, and convert the data collected in conformity with LOD standards. The VIVO ontology builds on prevalent LOD namespaces and, depending on the needs of the specialist community concerned, can be expanded.

How the Internet of Things is Promoting the Curation Effort

Update by Stephen J. Williams, PhD 3/01/19

Up till now, curation efforts like wikis (Wikipedia, Wikimedicine, Wormbase, GenBank, etc.) have been supported by a largely voluntary army of citizens, scientists, and data enthusiasts.  I am sure all have seen the requests for donations to help keep Wikipedia and its other related projects up and running.  One of the obscure sister projects of Wikipedia, Wikidata, wants to curate and represent all information in such a way in which both machines, computers, and humans can converse in.  About an army of 4 million have Wiki entries and maintain these databases.

Enter the Age of the Personal Digital Assistants (Hellooo Alexa!)

In a March 2019 WIRED article “Encyclopedia Automata: Where Alexa Gets Its Information”  senior WIRED writer Tom Simonite reports on the need for new types of data structure as well as how curated databases are so important for the new fields of AI as well as enabling personal digital assistants like Alexa or Google Assistant decipher meaning of the user.

As Mr. Simonite noted, many of our libraries of knowledge are encoded in an “ancient technology largely opaque to machines-prose.”   Search engines like Google do not have a problem with a question asked in prose as they just have to find relevant links to pages. Yet this is a problem for Google Assistant, for instance, as machines can’t quickly extract meaning from the internet’s mess of “predicates, complements, sentences, and paragraphs. It requires a guide.”

Enter Wikidata.  According to founder Denny Vrandecic,

Language depends on knowing a lot of common sense, which computers don’t have access to

A wikidata entry (of which there are about 60 million) codes every concept and item with a numeric code, the QID code number. These codes are integrated with tags (like tags you use on Twitter as handles or tags in WordPress used for Search Engine Optimization) so computers can identify patterns of recognition between these codes.

Now human entry into these databases are critical as we add new facts and in particular meaning to each of these items.  Else, machines have problems deciphering our meaning like Apple’s Siri, where they had complained of dumb algorithms to interpret requests.

The knowledge of future machines could be shaped by you and me, not just tech companies and PhDs.

But this effort needs money

Wikimedia’s executive director, Katherine Maher, had prodded and cajoled these megacorporations for tapping the free resources of Wiki’s.  In response, Amazon and Facebook had donated millions for the Wikimedia projects.  Google recently gave 3.1 million USD$ in donations.

Good and Bad News Reported for Ovarian Cancer Therapy

Reporter, Curator: Stephen J. Williams, Ph.D.

 

In a recent Fierce Biotech report

FDA review red-flags AstraZeneca’s case for ovarian cancer drug olaparib”,

John Carroll reports on a disappointing ruling by the FDA on AstraZeneca’s PARP1 inhibitor olaparib for maintenance therapy in women with cisplatin refractory ovarian cancer with BRCA mutation.   Early clinical investigations had pointed to efficacy of PARP inhibitors in ovarian tumors carrying the BRCA mutation. The scientific rationale for using PARP1 inhibitors in BRCA1/2 deficiency was quite clear:

  1. DNA damage can result in

1. double strand breaks (DSB)

  1.  DSB can be repaired by efficient homologous recombination (HR) or less efficient non-homologous end joining (NHEJ)

b. BRCA1 involved in RAD51 dependent HR at DSB sites

  1. In BRCA1 deficiency DSB repaired by less efficient NHEJ

 

 

2. single strand breaks, damage (SSB)

  1. PARP1 is activated by DNA damage and poly-ADP ribosylates histones and other proteins marking DNA for SSB repair
  2. SSB repair usually base excision (BER) or sometimes nucleotide excision repair (NER)

B. if PARP inhibited then SSB gets converted to DSB

C. in BRCA1/2 deficient background repair is forced to less efficient NHEJ thereby perpetuating some DNA damage pon exposure to DNA damaging agent

 

A good review explaining the pharmacology behind the rationale of PARP inhibitors in BRCA deficient breast and ovarian cancer is given by Drs. Christina Annunziata and Susan E. Bates in PARP inhibitors in BRCA1/BRCA2 germline mutation carriers with ovarian and breast cancer

(http://f1000.com/prime/reports/b/2/10/) and below a nice figure from their paper:

 

parpbrcadnadamage

 

 

 

 

 

 

 

(from Christina M Annunziata and Susan E Bates. PARP inhibitors in BRCA1/BRCA2 germline mutation carriers with ovarian and breast cancer.  F1000 Biol Reports, 2010; 2:10.)  Creative Commons

Dr. Sudipta Saha’s post BRCA1 a tumour suppressor in breast and ovarian cancer – functions in transcription, ubiquitination and DNA repair discusses how BRCA1 affects the double strand DNA repair process, augments histone modification, as well as affecting expression of DNA repair genes.

Dana Farber’s Dr. Ralph Scully, Ph.D., in Exploiting DNA Repair Targets in Breast Cancer (http://www.dfhcc.harvard.edu/news/news/article/5402/), explains his research investigating why multiple DNA repair pathways may have to be targeted with PARP therapy concurrent with BRCA1 deficiency.

 

However FDA investigators voiced their skepticism of AstraZeneca’s clinical results, namely

  • Small number of patients enrolled
  • BRCA1/2 cohort were identified retrospectively
  • results skewed by false benefit from “underperforming” control arm
  • possible inadvertent selection bias
  • hazard ratio suggesting improvement in progression free survival but higher risk/benefit

The FDA investigators released their report two days before an expert panel would be releasing their own report (reported in the link below from FierceBiotech)

UPDATED: FDA experts spurn AstraZeneca’s pitch for ovarian cancer drug olaparib

in which the expert panel reiterated the findings of the FDA investigators.   The expert panel’s job was to find if there was any clinical benefit for continuing consideration of olaparib, basically stating

“This trial has problems,” noted FDA cancer chief Richard Pazdur during the panel discussion. If investigators had “pristine evidence of a 7-month advantage in PFS, we wouldn’t be here.”

The expert panel was concerned for the above reasons as well as the reported handful of lethal cases of myelodysplastic syndrome and acute myeloid leukemia in the study, although the panel noted these patients had advanced disease before entering the trial, raising the possibility that prior drugs may have triggered their deaths.

 

This was certainly a disappointment as ….

it was at last year’s ASCO (2013) that investigators at Perelman School of Medicine at the University of Pennsylvania and Sheba Medical Center in Tel Hashomer, Israel presented data showing that in 193 cisplatin-refractory ovarian cancer patients carrying a BRCA1/2 mutation, 31% had a partial or complete tumor regression. In addition the study also showed good response in pancreatic and prostate cancer with tolerable side effects.

 

See here for study details: http://www.uphs.upenn.edu/news/News_Releases/2013/05/domchek/

 

As John Carrol from FierceBiotech notes, the decision may spark renewed interest by Pfizer of a bid for AstraZeneca as the potential FDA rejection would certainly dampen AstraZeneca’s future growth and profit plans. Last month AstraZeneca’s CEO made the case to shareholders to reject the Pfizer offer by pointing to AstraZeneca’s potential beefed-up pipeline. AstraZeneca had projected olaparib as a potential $2 billion-a-year seller, although some industry analysts see sales at less than half that amount.

A company spokeswoman said the monotherapy use of olaparib for ovarian cancer assessed by the U.S. expert panel this week was only one element of a broad development program.

 

 

Please see a table of current oncology clinical trials with PARP1 inhibitors

at end of this post

 

However, on the same day, FierceBiotechreports some great news (at least in Europe) on the ovarian cancer front:

 

EU backs Roche’s Avastin for hard-to-treat ovarian cancer

As Arlene Weintraub   of FierceBiotech reports:

EU Committee for Medicinal Products for Human Use (CHMP) handed down a positive ruling on Avastin, recommending that the European Commission approve the drug for use in women with ovarian cancer that’s resistant to platinum-based chemotherapy. It’s the first biologic to receive a positive opinion from the CHMP for this hard-to-treat form of the disease.

Please see here for official press release: CHMP recommends EU approval of Roche’s Avastin for platinum-resistant recurrent ovarian cancer

 

EU had been getting pressure from British doctors to approve Avastin based on clinical trial results although it may be important to note that the EU zone seems to have an ability to recruit more numbers for clinical trials than in US. For instance an EU women’s breast cancer prevention trial had heavy recruitment in what would be considered a short time frame compared to recruitment times for the US.

 

Below is a table on PARP1 inhibitors in current clinical trials (obtained from NewMedicine’s Oncology KnowledgeBase™). nm|OK is a relational knowledgeBASE covering all major aspects of product development in oncolology. The database comprises 6 modules each dedicated in a specific sector within the oncology field.

Clinical History Refer to the Combination Trial Module for trials of Avastin in combination with various chemotherapeutic regimens.According to results from the AURELIA clinical trial (protocol ID: MO22224; 2009-011400-33; NCT00976911), the median PFS in women with progressive platinum resistant ovarian, fallopian tube or primary peritoneal cancer treated with Avastin in combination with chemotherapy, was 6.7 months compared to 3.4 months in those treated with chemotherapy alone for an HR of 0.48 (range =0.38–0.60).. In addition, the objective response rate was 30.9% in women treated with Avastin compared to 12.6% in those on chemotherapy (p=0.001). Certain AE (Grade 2 to 5) that occurred more often in the Avastin arm compared to the chemotherapy alone arm were high blood pressure (20% versus 7%) and an excess of protein in the urine (11% versus 1%). Gastrointestinal perforations and fistulas occurred in 2% of women in the Avastin arm compared to no events in the chemotherapy arm (Pujade-Lauraine E, etal, ASCO12, Abs. LBA5002).A multicenter (n=124), randomized, open label, 2-arm, phase III clinical trial (protocol ID: MO22224; 2009-011400-33; NCT00976911; http://clinicaltrials.gov/ct2/results?term=NCT00976911 ), dubbed AURELIA, was initiated in October 2009, in Europe (Belgium, Bosnia and Herzegovina, Denmark, Finland, France, Germany, Greece, Italy, Netherlands, Norway, Portugal, Spain, and Sweden), and Turkey, to evaluate the efficacy and safety of Avastin added to chemotherapy versus chemotherapy alone in patients with epithelial ovarian, fallopian tube or primary peritoneal cancer with disease progression within 6 months of platinum therapy in the first line setting. The trials primary outcome measure is PFS. Secondary outcome measures include objective response rate, biological PFS interval, OS, QoL, and safety and tolerability. According to the protocol, all patients are treated with standard chemotherapy with IV paclitaxel (80 mg/m²) on days 1, 8, 15 and 22 of each 4-week cycle; or IV topotecan at a dose of 4 mg/m² on days 1, 8 and 15 of each 4-week cycle, or 1.25 mg/kg on days 1-5 of each 3-week cycle; or IV liposomal doxorubicin (40 mg/m²) every 4 weeks. Patients (n=179) randomized to arm 2 of the trial are treated with IV Avastin at a dose of 10 mg/kg twice weekly or 15 mg/kg thrice weekly concomitantly with the chemotherapy choice. Treatment continues until disease progression. Subsequently, patients are treated with the standard of care. Patients in arm 1 (n=182), on chemotherapy only may opt to be treated with IV Avastin (15 mg/kg) three times weekly. The trial was set up in cooperation with the Group d’Investigateurs Nationaux pour l’Etude des Cancers Ovariens (GINECO) and was conducted by the international network of the Gynecologic Cancer Intergroup (GCIG) and the pan-European Network of Gynaecological Oncological Trial Groups (ENGOT), under PI Eric Pujade-Lauraine, MD, Hopitaux Universitaires, Paris Centre, Hôpital Hôtel-Dieu (Paris, France). The trial enrolled 361 patients and was closed as of May 2012..Results were presented from a phase II clinical trial (protocol ID: CDR0000068839; GOG-0170D; NCT00022659) of bevacizumab in patients with persistent or recurrent epithelial ovarian cancer or primary peritoneal cancer that was performed by the Gynecologic Oncology Group to determine the ORR, PFS, and toxicity for this treatment. Patients must have been administered 1-2 prior cytotoxic regimens. Treatment consisted of bevacizumab (15 mg/kg) IV every 3 weeks until disease progression or prohibitive toxicity. Between April 2002 and August 2004, 64 patients were enrolled, of which 2 were excluded for wrong primary and borderline histology and 62 were evaluable (1 previous regimen=23, 2 previous regimens=39). The median disease free interval from completion of primary cytotoxic chemotherapy to first recurrence was 6.5 months. Early results demonstrated that some patients had confirmed objective responses and PFS in some was at least 6 months. Observed Grade 3 or 4 toxicities included allergy (Grade 3=1), cardiovascular (Grade 3=4; Grade 4=1), gastrointestinal (Grade 3=3), hepatic (Grade 3=1), pain (Grade 3=2), and pulmonary (Grade 4=1). As of 11/04, 36 patients were removed from the trial, including 29 for disease progression and 1 for toxicity in 33 cases reported. Preliminary evidence exists for objective responses to bevacizumab (Burger R, et al, ASCO05, Abs. 5009).An open label, single arm, 2-stage, phase II clinical trial (protocol ID: AVF2949g, NCT00097019) of bevacizumab in patients with platinum resistant, advanced (Stage III or IV), ovarian cancer or primary peritoneal cancer for whom subsequent doxorubicin or topotecan therapy also has failed was initiated in November 2004 at multiple locations in the USA to determine the safety and efficacy for this treatment.A multicenter phase II clinical trial was initiated in April 2002 to determine the 6-month PFS of patients with persistent or recurrent ovarian epithelial or primary peritoneal cancer treated with bevacizumab (protocol ID: GOG-0170D, CDR0000068839, NCT00022659). IV bevacizumab is administered over 30-90 minutes on day 1. Treatment is repeated every 21 days in the absence of disease progression or unacceptable toxicity. Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter. A total of 22-60 patients will be accrued within 12-30 months. Robert A. Burger, MD, of Chao Family Comprehensive Cancer Center is Trial Chair.This trial was closed in August 2004.

In a followup to this original posting A Report From the Institute of Medicine of the National Academies of Sciences, Engineering, and Medicine entitled

Evolving Approaches in Research and Care for Ovarian Cancers

was generated in a ViewPoint piece in JAMA which discussed their Congressional mandated report on the State of the Science in Ovarian Cancer Research, titled

Ovarian Cancers: Evolving Paradigms in Research and Care 

highlights some of the research gaps felt by the committee in the current state of ovarian cancer research including:

  • consideration in research protocols of the multitude of histologic and morphologic subtypes of ovarian cancer, including the feeling of the committee that high grade serous OVCA originates from the distal end of the fallopian tube (espoused by Dr. Doubeau and Dr. Christopher Crum) versus originating from the ovarian surface epithelium
  • a call for expanded screening and prevention research with mutimodal screening including CA125 with secondary transvaginal screen
  • better patient education of the risk/benefit of genetic testing including BRCA1/2 as well as in consideration for PARP inhibitor therapy
  • treatments should be standardized and disseminated including more research in health outcomes and decision support for personalized therapy
